In the building trade, you're lucky still to be working at sixty, its still hard dirty and COLD for the guys on the scaffold.
I'm fortunate to still be working, but many of the guys who served their time with me are crippled or have no quality of life in retirement.
Hard manual labour leaves little scope to develop other interests, and many turn to drink and smoking as a means of relaxation.

In the world of bricks and mortar, or 60ft roofs, the idea of many working till they are 70 is ridiculous.

There are two worlds, the world of white collars and water coolers, and the world of icy wet cloths, 40ft up on an exposed gable, looking forward to getting some feeling back into your hands over the old gas ring!
